A l plicationq unez' 'i,1941;;serial l ioe icmllfi My invention relates generallyto stuffing machines applicable for various purposes as wellas for stufiing Wiener-casings; said machinesflcom prisingcylinders having air-tight covers carried by laterally swinging yokes and freelymoving pistons in the cylinders operated by air "or other fluid under pressure. And the principal object' oi my present invention has been to design and ,cbnstruct two i such cylinders stationed side by side and adapted to operate together or separately at the option of the operator, each cylinder containe ing different ingredients. Another-object of my invention has been to designan outlet 'for said ingredients from each of said cylinders, said out lets being adjacent and opposite, and adapted for the entrance of the conventional threaded nipple and the tightly-fitting ingredient tube with its I valve and extension stufiing-nozzle, whichin'my invention is double, comprising a small inner tube anda larger outer tube. I have 'also'aimed to have a reasonably large cleaning hole plugged with a threaded stopper, in opposite sides of each of said cylinders, near ,thebottoms thereof. ,I also have threaded holes near the bottom'slof each ,.cylinder, designed for the entrance of thefluid pressure for operating the pistons therein.\...Other obpects of my invention will be disclosed in the progressof this specification.

' The foregoing objects have been-attainedv in instant invention; and'my new and useful stuffing machineillustrated in the accompanyingdraw ing iorminga part of. this specificationis apractical device embodying the aforesaid novel means and other new and useful details of construction,- arrangement and combination of parts,--al1- of which 'tOgether with their functions willbe cle-' scribed with'reference to said drawing, andwill be definitely pointed outin the claim that" follows this description, so that any person skilled in the art, may.be able to construct and use'this inven- "In said drawing: 1 t s Fig. 1 is. a full view ofthe front-par-ti'of my. stufiing machine, partly -inelevation and partlyin section, showing the two adjacent verticallyxdisa posed cylindersset side by side, wit'hltheir adjae cent I ingredient outlets near the,- tops of 'said cylindersnfl Q, i v I Fig. 2 is aplan view of the upper part'ofb'oth said adjacent cylinders, with :theflaterallyswing Fig: 3 1s an .elevationalview, partlyin section, of afragment ofthe beveledcylinden 'cover, showin'gthe'air-tight joint between the beveledi'cover and thecorrespondinglybeveledupper rim ofzsaid cylinder;

Cylinders land l.are prqvidedf respectively ithi e r i g' Pistons L w nd. p rae ew means of compressed air or other fluids under pressure, admitted thereunderthrough the respective threaded holes lb and Ib'. 011 these 7 cylinders I and 'I"j'I"havec'ast heavy integral pillowb l'oclsts;respectively; 10 and Ic-for-th e puring yokes and the appended cylinder scoversain place, showing the relative-positions of thebutlet tubes, the cutofi valves; the ingredient tubes andthe conical ingredienthoodr pose'iof anchoring said 'cylinders land l'respectively, t'o'thefioor 3 withheavy'irietal rods id and Ifd; extending down through said floor to the .basement fiodring 3,1 wheref'said-'metal rods are securelyanchored- Said threaded metal rods'ld' andild are provided respectively with :th'readed floor flanges la: 'anfd il ;r for anchorage and ad; justm'ent. in the floort. -have provide'd the istonma and 1 a, respectively withfmetal-rod shanks fastenedon the underside "thereof and passing 'air-tightithroug h the-solid metal bottoms said cylinders" 'and 'theffloor '3 to be anclifored and a'dj u'sted in the cross-beam 5 aaaptdjto'sliae evenly up and down on' -the metal rods ldandi-"d between-'th floor 3 and the basement flooring 4Q And-the cross' -beam fi' I have fashioned in -tw'd sections, lz and"1-'z',"se'curely bolted together' at" the joint 6 therein; for, sometimes I want the pistons Ia and Ia to operate together and sometimes separately. For the purpose of cleaning out that portion of said cylinders under the pistons, Ia, la, I have designed reasonably large cleaning ports, ly and I respectively, in opposite sides of each of the cylinders, l and 1', near the bottoms thereof; said ports being adapted to be plugged with threaded stoppers.

In Fig. 2 I have shown the adjacent outlettubes 1 and I, and the pillow-blocks,,8 and 8 adapted to support the laterally-swinging yokes, 9 and 9'. These outlet-tubes and pillow-blocks are cast integral with the cylinders I and I. On

the front ends of the outlet-tubes, I and 1', I

have fitted the cut-off valves 1a and 'Ia and stufling nozzle 10, which is adapted to hold the.

casing of a sauerkraut-filled wiener. The front ends of the stufling nozzles, 10 and 'lc terminate in the same vertical plane, at right-angles thereto. The rear ends of the outlet-tubes, I and 1' may be outfitted with fixtures similar to the fixtures in the front ends of said tubes.

This arrangement would double the number of weiners or other designs of food-products produced in any given time,

The inner ends of the laterally-swinging yokes, 9 and 9', are pivoted in the inner adjacent upper pillow-blocks, 8 and :8, and are securely held in their service positions by means of the pivots, 9a and Qa; said pivots being secured with threaded nuts fixed on the threaded end of said pivots. And the outer endsof said swinging yokes are clamped on the outer pillowblocks, 8 and 8', securely held in their fixed positions by means of the pivots, 9b, 9c and 9'1), 9'0, said pivots being secured with threaded-nuts fixed on the threaded ends of said pivots.

The cylinder-covers, II and H-, are carried swiveled on the lower ends of the threaded bolts, l2 and 12', and said covers can be readily forced open or closed air-tight by screwing said bolts upward or downward in said .yokes by means of the cruciformlevers, I2a and 'I2"a, rigidly fixed on the upper ends of said bolts at right-angles thereto. v V

Operation, of said machine In the production of sauerkraut-filled wi'- ners, I first raise the cylinder-covers, H and H. by rotating the threaded bolts t2 and I2; then, after loosening the clamping pivots, 9b, 9c and 9'1), 9'0, I swing the yokes, 9 and 9' carrying the covers, II and II with them out away. from the open tops of the cylinders I and 1. I I then fill into the open cylinder l a predetermined quan'-' tity of my ground-meat ingredient prepared like ordinary Wiener ingredient. And into the cylinder 1 I fill a predetermined quantity of sauerkraut-ingredient prepared according to my formula, giving the sauerkraut theright consistency to be forced through the ingredienttube, 'l'b andthe small stufiing nozzle .110 with a pressure equal to the pressure required, .to force the ground meat of the ordinary Wieneringredient through theingredient-tube Jb and "only :one cylinder, namely, cylinder I.

the large stufiing nozzle To, which holds the wiener-casing stretched thereon. I now swing the yokes 9 and 9 carrying the cylinder-covers, H and II', back over the tops of the cylinders, l and l and screw said covers down air-tight in the beveled rims of said cylinders, andtighten the clamping pivots 9b, 9c and Qb, 9'c, to hold said yokes in their service positions. And now that the air-pressure tubes are connected up to the threaded holes lb and I'b; and the cut-off valves la and Ta are open, I am ready to produce sauerkraut-filled wieners When I desire to make other designs of foodproducts with this said machine, I would use And in this event, I would cut off the air-pressure from cylinder 1 and I would also remove the two .bolts from the joint 6 in the cross-beam 5, so

that the cylinder I may operate freely without disturbing the piston Ia in the cylinder I. Then I clean out the cylinder l and its tubes and cut-off valve and unscrew both stufiing nozzles and remove them from the hood I0. I then fix into the outer end of the hood 10 any design nozzle I select for my other food-product; and after preparing my new ingredient for the other designs of food-products, I fill the cylinder l with a predetermined quantity of the new ingredient for the other designs of food-products; and then proceed to produce them under airpressure in quantities desired,

Thus it can readily be seen that I have de signed and developed a new and efficient stuffing machine adapted for rapidly stuifing sauerkraut-filled wieners and for forming and producing other designs of food-products. But in the description of saidnew and useful machine, 'as set forth in the foregoing specification, it sh'ou'ldbe well understood that the specific detail of the various parts of the instant embodiment of my present invention, as I have illustrat'ed in the drawing thereof and fully described, are not to be considered as limitations in the construction of my new device; and that while keeping within the scope of my invention scope of my invention and claim.

Now, having thus described the various features of my new invention, the detail construction, arrangement and combination of its parts, as well as their functions and the ways and means of assemblage, operation and application; those features and accessories of my new device for the purposes hereinabove explained, on which I desire Letters Patent granted to me, 1': have set forth specifically in the followingclaim.

I: claim:

Ina stuffing machine of the kind shown and described, the combination of two adjacent vertical food-cylinders resting uponthe fioor above a b'asement; said :cylinders having air-tight covers j'and provided with air-tight freely moving pistons opera'tive by -'compressed air or-othe fluids under pressure in said cylinders; integral pillow-blocks or heavy lugs cast on the opposite sides of said cylinders near thebottoms thereof;

said c'ylinders beingheld in place-by means of postsanchored in said basement and passing up throughsaid floor andfastened in said lugs; a cross-beam in said basement adapted to slide up anddown on said posts; vertica l'rods fixed on the under sides of said pistons and extending valves, having fixed therein curved food tubes extending into a conical hood; and double 'stuf- 'fing nozzles fixed in said hood, comprising a small inner tube connected with one of said cylinders containing one kind of ingredient, and a larger outer tube connected with the other cylinder containing another kind of ingredient, said outer tube being adapted to hold the casing of a Wiener.
